I think they've got you TBH.
airbnb is literally in your domain name.
It'd be different if it was in marketing materials/etc but its in your domain name...
If you'd registered "itslikeabnbforyourdog" you'd probably be in a lot less of a predicament.

For Airbnb, if they don't defend their trademark, they can lose the trademark and the right to enforce it, so they must go after everyone who is using it that doesn't have permission. And your usage is a direct reference to their trademark so yea you are in violation here. They obviously don't feel like you are being malicious, hence you got a simple polite form letter and a request to comply not something more aggressive.
The exception would be if you can show the letter sequence really is coincidental, but the case we're discussing is a blatant attempt to cash in on Airbnb's brand.
